pgbouncer process exporter group is not working on pgbouncer production nodes
pgbouncer is a single threaded process and as such we need to monitor the CPU usage of these processes in order to monitor for saturation.
Work has been done on this, and this monitoring appears to be working for the patroni fleet, but not (ironically) for the pgbouncer fleet.
This should be corrected.
Minor corrective action for https://gitlab.com/gitlab-com/gl-infra/infrastructure/-/issues/9966
